That doesn't seem possible. And the hose is not just held on by vacuum; it should resist being pulled off unless the hose is worn/stretched/cracked. If that is the problem, cutting off the damaged part (which should only be a short amount) should resolve the problem long enough to see if there is an improvement. The vacuum hose on my 1991 9000T doesn't yet show any of these signs, although the valve itself failed and needed replacement.
